The 37-year-old actress continued: "I don't really think you get a sense of me, sexually, and that's why I have really great relationships with straight men."

Newton also admitted to having a crush on John Cusack, saying: "He's so sweet! John is smart; he's got great integrity and he's got that look. Like he would know what to do with you. He's a very sexy man. Even my mum was like, 'Ooh yes!'"
